Essays on Stem

Abstract:

Medicine and science had always maintained a steady flow of debates by the beginning of the 20th century with the ongoing increase of diseases, and virus mutations keeping up with the modern technology. Medicines had to be updated regularly to ensure that mutations would not influence a person’s sickness and overall health. It is common to see various medical procedures claiming that they can cure a disease or complication without the need to pay medicines regularly. One of these offerings is known as stem cell treatment, which uses stem cells to repair damage tissues or cure diseases. While Continue reading...

Abstract

Stem cells research and particularly stem cell research is an area that has continually stirred up moral, spiritual and cultural dilemmas. Several arguments have been advanced both for and against stem cell research even as advances that are being made in the field of stem cell research continually evolve making it closer to becoming a widely practiced scientific application. Stem cells are widely studied because of their inherent ability to be renewed and regenerated in addition to their ability to adapt to different environments. Some of the benefits of stem cell research are: stem cells can be used Continue reading...

INTRODUCTION

The human body consists of tissues and organs that contain over 200 different cell types.1 these cells carry out all the functions required for viability and reproduction. It was argued long ago, that in some tissues, the differentiated cells have a shorter life span and that they are not able to self -renew.2 This led to the notion that such tissues are maintained by cells that have an extensive renewal capacity, and the ability to differentiate and generate daughter cells. These cells were termed as ‘stem cells”.2 Stem cells generate only the differentiated lineages of the tissues they Continue reading...

Healing the Future

INTRODUCTION
In a diverse nation like the United States there are many ideologies, philosophies, cultural “norms,” and belief systems, it is not really surprising that people are not always going to agree. There are many legal, political, and social issues that raise ethical questions that the public cannot agree upon how best to approach and address the debated issues. One of the most heatedly debated issues that exist today is the concerns surrounding stem cell research. Stem cell research has the potential to change the field of medicine and how people are healed. However, all of that potential is Continue reading...

Besides the benefits from the research in stem cells, the research has proven to be one of the most controversial issues in the modern world. The prime concern is deciding whether its continuity is right or wrong. Many are arguing the issue of morality which involves the use of human embryos, genetic engineering, cloning and the biological impacts resulting from the research. It has spanned a strong debate in regard to its credibility in regard to ethical concerns primarily about creation, destruction and also the use of embryos. It does not stop there because of other issues raised about Continue reading...

INTRODUCTION

The debate over stem cell research, and whether or not it should be made legal, is very complicated and long-standing. Stem cell research involves investigating whether or not embryonic stem cells can be used to potentially cure a number of diseases, including Parkinson’s, Alzheimer’s, and many others. The theory is that, since stem cells are able to differentiate into any other cell in the body, that they can be used to create healthy cells where once there were cancer cells, thus treating the disease. Stem cells have already been used to repair disease-ridden tissue successfully in Continue reading...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects Continue reading...

Stem cells have a major role in the biological processes. Because of the ability of the stem cells to divide, they are important in the development of an organism and repair of damaged tissues. Stem cells have the potential to treat degenerative diseases like diabetes, Parkinson’s and heart disease.
The unique characteristics of stem cells include its ability to divide, replicate and renew themselves for long periods. They are unspecialized; thus, they can produce specialized cell types. They can differentiate into other cells. Stem cells have regenerative abilities which make it useful in therapeutic interventions. They can produce Continue reading...

INTRODUCTION:

The stem cell research has been debated ever since the birth of it. However, the categorization of the stem cell research has been defined in a wrong manner. Moreover, the media is sensationalizing the topic. This has resulted in a wrong notion that all stem cell research is unethical. This is a wrong notion of the research because there are two types of stem cell research. The adult stem cell research is ethical than the embryonic stem cell research.
Adult stem cell research refers to the usage of matured cells from mature adult human being without killing the host. Continue reading...

Embryonic stem cells have the tendency to divide for long duration and continue to have their capacity to make all cell types within the organism. Thus they are termed pluripotent stem cells. Embryonic stem cells are obtained from embryos which are particularly obtained from eggs that have been fertilized in vitro. The embryonic stem cells are recognized by two distinctive properties – their pluripotency and their ability to replicate indefinitely.
Cell culture is a procedure wherein the embryonic stem cells are grown inside the laboratory. The human embryonic stem cells are first separated by removing the inner cell mass into Continue reading...

Introduction:

Stem Cell Research has been one of the most controversial breakthroughs of science since the late 1990’s. The extraction of the human embryonic cell on that decade has made various responses in the medical field. This has opened many doors for many scientists that are highly interested in regenerative medicine. Additionally, this has also opened new debates about the ethics of the process of harvesting stem cells. There are two types of stem cell research. The first one is known as the embryonic stem cell research. The second one is named as the adult stem cell research (Shapiro, Continue reading...

According to the Merriam-Webster dictionary, stem cell is an undifferentiated cell that can generate other cells which makes up specialized organs and tissues in living organisms. Stem cells are of two major types namely; adult stem cells and embryonic stem cells. Embryonic stem cells are found inside an embryo that is in its earliest developmental stage i.e. blastocyst, these stem cells eventually give rise to the adult organisms. The adult cells helps in the regeneration of worn out tissues and are located in some of the tissues in the body of living things e.g. the intestine lining, the skin’ Continue reading...

Abstract

This paper describes and discusses the various types of human stem cells, including those in early-stage embryos (the blastocyst) and those present in adult tissue, explaining the practical uses of the various types in the medical field, where stem cells can be used to repair damaged tissue and organs. Although the adult stem cell types offer fewer possibilities for medical applications than the embryonic type, their use is less ethically controversial because it does not require destruction of a living albeit very early stage embryo. Research into stem cell applications is finding improved techniques. These include the treatment of Continue reading...

The adult stem cells refer to the undifferentiated cells that are found all through the body after the body has undergone development (Jurukovski, 2012). The adult stem cells multiply through division in order to replenish the cells that are dying as well as regenerating the tissues that have been damaged. These cells are also referred to as somatic stem cells and are found in juvenile and adult animals as well as human bodies. The ability of the adult stem cells to divide or have an indefinite self–renewal has gathers great interest in science. The cells have been suggested Continue reading...

Stem Cell Research

Stem cells comprise natural in the human body capable of differentiating into different specialized cells (Cummings, 2009). These cells are also capable of self-renewal whereby they reproduce into more stem cells. Mammals produce two types; adult and embryonic stem cells. Embryonic stem cells are harvested from the inner cell mass of embryos in the blastocyst stage. Embryo cells differentiate into all the organs and tissues that form the human body. Adult stem cells are present in various tissues within the body (Cummings, 2009). These cells are responsible for body repairs and replenishment.

Stem cell research is Continue reading...

Stem cell research has been termed by the medical research fraternity as one of the greatest milestones in human health science. Stem cells can be defined as any kind of cell that can divide through mitosis and thereby specialize into any of the several different kinds of cells found in the human body. This specialization of the cells into any of the functional cell in the body means that doctors can use it to heal many cell-associated diseases. For example, there diseases and condition that lead to the damage of the neural cells in the brain or the spinal Continue reading...

Stem cell research has been termed by several health practitioners and scholars as one of the greatest milestones in medical research. Stem cells can be defined as any cells that have the ability to divide and thus can be specialized into any of the different kinds of cells found in the body . Such specialization and growth of cells into any of the functional cells implies that physicians can use the technology to cure many cell-related diseases. For instance, stem cells can be used to replace damaged cells due to cancer. Other diseases may lead to the damaging and degradation Continue reading...

Stem cells are possess the ability to develop into different cell types in the body. They can also serve as a repair mechanism, dividing several times to replenish damage tissue. Stem cells are unspecialized cells, which can renew themselves through cell division, sometimes, even after a long period of inactivity. Stem cells can also be induced, under physiologic or experimental conditions to produce tissue specific or organ specific cells (News Medical, 2012).
Embryonic stem cells are stem cells derived from the early stage of division of human embryos shortly after fertilization. They are isolated from the inner cell mass Continue reading...

Cells built to function in a specific organ system and perform out specific purpose. White blood cell meant to fight off diseases while red blood cells caries oxygen. Pluripotent stem cells that founds in embryos can trigger rise to all of the cells found in human body. Diverse –cells found in the brain, multipotent stem cells in bone, skin, and heart. Multipotent stem cells found in babies fetus umblicord and also in adults. Their growth development is limited only Continue reading...

Ethics of Stem Cell Research

Stem cells are central to newly developed therapies for curing degenerative diseases in humans. This is attributed to a very attractive feature of stem cells: their ability to produce a wide variety of other types of cells. Starting from stem cells, it is possible therefore to produce blood, brain, liver, muscle or essentially any type of specialized cell in a process called differentiation. Accordingly, with these therapies is now possible to aspire to find solutions to conditions that require organ or tissue replacement with a reduced rejection probability or even immune response (Juengst E). Patients with conditions like cirrhosis, Continue reading...

‘Stem cells’ is one of the widely discussed topics in recent years. Scientific progress led to the understanding the mechanism of stem cells and their use in therapeutic applications, which involve the treatment of cancer, diseases related to heart, brain and many others . Stem cells are a distinct type of cells, which are capable of regenerating themselves through the process of cell division. Under experimental conditions, stem cells have the ability to transform into tissue-specific or organ-specific cells. Since stem cells are unspecialized cells, they are capable of producing specialized cells through the process of differentiation . While embryonic stem Continue reading...

Stem cells is biologically fundamental structures found in all multi cellular organisms. These cells divide through the process of mitosis. Moreover, they possess a characteristic of dividing into more specialized cells and can also form more stem cells. Mammals possess two main types of stem cells. These include the progenitor cells and the embryonic stem cells. Another fundamental category of the stem cells includes the adult stem cells. All these kinds of stem cells possess specific kinds of characteristics and functions. The progenitor cells as well as the adult cells provide a repairing function in the bodies of adults.

Introduction

There was a time when USA was far ahead of its competitors in innovation but in recent times the trend has seen a steep decline. Not only in innovation, America is also falling behind other countries in the area of high skilled workers literate in math, science and technology. There was a time, not long ago, when "the United States set the pace as the world’s leading innovator: from the personal computer to the internet, from Wall Street to Hollywood, from the decoding of the genome to the emergence of Web 2.0" but slowly it is "losing its Continue reading...

Stem Cell Research and Ethical Thinking

There has been a lot of debate surrounding embryonic stem cell research for quite a long time. The progress of stem cell science has slowed down because of the controversy. The main issues that have tormented the progress of stem cell research have been addressed and the ethical fault lines that will probably continue have been identified in the article “Update: Stem-Cell Research” ("Update: Stem-cell research," 2007). Although the restrictions on federal funding for embryonic stem cell research have been removed by President Obama, this article takes a look back and explores the factors that led President Bush to “ Continue reading...

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and further divide through the process of mitosis to produce more cells. Stem cells are found in multicellular organisms; however, in mammals there are two broad categories adult stem cells that are found in diverse tissues, and embryonic stem cells that are isolated from the inner cell mass of the blastocyst. Stem cells and progenitor cells act as a system that repairs the body in case it is injured as well as replenishing tissues (Humber 105). However, in the developing embryo stems cells differentiate into specialized cells Continue reading...

Various countries regulate such research in different ways as the subject still carries a divided opinion. What makes the topic of use of embryos so tricky to resolve, and is it so tough to resolve the issues? The research use of human embryos is currently a high ethical and political agenda in many countries. Despite the possible benefit of the research, their use is contentious because they are derived from early embryos. In this essay, some of the ethical issues surrounding the use Continue reading...

Introduction

Stem cells refer to a group of undifferentiated cells that have the potential to develop or renew into different cell types. These cells come from two main sources, that is, the adult stem cells and embryonic stem cells. On the other hand, stem cell research focuses on scientific developments, scientists are taking to restore, reshape or grow cells. Stem cell research is a topic that generates debate in many places because it involves the use of science on cells. Some people consider this research as morally wrong while others important. This paper will critically evaluate both sides of the Continue reading...

Annotated bibliography
Over the years there has been unending debate of whether the state should use federal funding to support the field of stem cell research or whether stem cell research should be allowed at all. According to Goodwin, This debate which has been looming on for centuries brings our thinking to the ethical question of biotechnological research and the moral use of human organs – the basic fundamental cells of life such as the stem cell. Those supporting the research and even those corporations funding it have proposed their support throwing weight on the fact that unused frozen embryos Continue reading...

What is the evidence that convinces you Cancer Stem Cells are a subpopulation of tumour cells with distinct tumour‐initiating capacity?
What are cancer stem cells (CSCs)? They are cancer cells that have similar characteristics as normal stem cells. CSCs have the potential to give rise to other cells types, and thus are tumorigenic in nature. These cells can generate tumors via stem cell processes of self-renewal, as well as differentiation into different cells (Wang, Chiou & Wu, 2013). CSCs have been found to persist in tumors in the form of a district population and often cause relapse and Continue reading...

Stem cells can be referred to as undifferentiated biological cells, which can form specialized cell when they differentiate and have the ability to divide to form more stem cells. Research scientists have discovered a number of potential applications of the stem cells. For instance, mesenchymal stem cells are presently being tried as a potential treatment for graft versus host disease as well as graft rejection. This is after trials on a number of animals demonstrating that treatments with allogenic stem cell were not rejected and demonstrated no difference in capabilities to heal as compared to autologous stem cells. This Continue reading...

Overview of egg stem cells

Abstract
Currently, the ability of a woman to produce eggs is limited by the age of the woman and the quality of the eggs that the older women produce. The research that was done about stem egg cells can address the issues of age and quality of eggs. Egg stem cells are eggs that are able to differentiate, or develop to other types of cells of the human being. There are possibilities that the new discoveries of egg stem cells is that they could be used and developed into new eggs. Even if this is not a possibility they Continue reading...

During the last part of the 20th century, the science community began to do things that only a few years before would have been unimaginable. Since 1981 when embryonic stem cells were first isolated from mouse embryos research in molecular biology involving embryonic stems cells has moved quickly, and just as quickly ethic concerned having a background in Christian religious doctrine has fueled a strongly polarized debate as to whether or not such research is ethical. Research in this area has led to accomplishments such as cloned sheep and offers a novel way to treat disease.
Previously in the Continue reading...
